Question

Find the total surface area of a solid cylinder, whose diameter of the base and the height are 14cm and 10cm respectively.

Answer 1

TSA of cylinder is 2πr(r+h)
so, 2*22/7*14/2(14/2+10)
2*22/7*7(7+10)
2*22(17)
44(17)
748cm^2

Answer 2

Hey there!

Diameter, d = 14 cm
Radius, r = d/2 = 14/2 = 7 cm

Height, h = 10 cm

T.S.A. of Cylinder = 2πr(r+h)

= 2 × 3.14 × 7 × (7+10)

= 43.96 × 17 cm²

= 747.32 cm²
